Abstract :
Through recent years, several types of research have been performed about steel plate shear walls numerically, experimentally and a combination of these two methods. Scaled samples have been implemented to make transportation and movement processes easier. However, the accuracy of samples with real scale is of concern. In this research -which has been performed experimentally and by software implementation-, at first, cyclic loading was applied on a single-story, single-span steel shear wall sample made with a one-third scale in the laboratory and then it was modeled in ANSYS and loaded in the same condition. The comparison between these two methods represents an acceptable conformation. After the verification accomplished, various conditions were modeled and analyzed in the software as one-fifth, one-fourth, one-third, one-second, two-third and one scale. The results indicate that averagely, a 25% decrement of maximum shear is observed in the scaled models but the result from contours shows a good conformation in the scaled results and indicates their reliability.
